NHTSA Complaint #11160859 — 2012 HYUNDAI SONATA

HAD MOTOR REPLACED FROM A PREVIOUS RECALL, 4DAYS AFTER THIS FIX I NOTICED A ROUGH IDLE. WENT TO NUMEROUS SHOPS INCLD DEALERSHIP WAS TOLD BY DEALERSHIP THAT RECALL WAS DONE AND ANY OTHER REPAIRS WOULD BE OUT OF POCKET. PROBLEM HAS PROGRESSED FROM ROUGH IDLE AND ENGINE NOISE TO POOR ACCELERATION AND MISTIMED BOOSTS. AS IN WHEN ENTERING HIGHWAY CAR DOESNT ACCELERATE VERY FAST VERY LONG DELAY BEFORE BOOST INTIATES. ONCE AT DESIRED SPEED WHEN SLOWING DOWN CAR BOOSTS WITHOUT PRESSURE TO ACCELERTATOR!!! NOW THAT WINTER HAS ARRIVED, SPORADICALLY ON COLD START CAR IDLES EVEN ROUGHER AND SOUNDS AS IF IT WITH SHUT OFF. WHEN DRIVING IN TRAFFIC CAR IDLES ROUGH THEN SHUTS OFF!! NO POWER STEERING! NO LIGHTS ! NO POWER! THIS HAPPENED WHILST CAR IS IN DRIVE AND IN MOTION! I TRY TO AVOID HWYS AND NIGHT TIME DRIVING WHEN I CAN AS IM SCARED TO DEATH OF THIS CAR. I PURCHASED IT USED IN DEC2017 11 DAYS LATER INTIAL ISSUES BEGAN WITH CAR LOOSING POWER. NOW AFTER ISSUE WAS "FIXED" BY REPLACEMENT MOTOR SAME INTERMEDIATE LOST OF POWER ISSUES AGAIN BUT WITH THE ADDED BOOSTING ISSUE AS WELL NOW.
